Answer:
Option B.
Step-by-step explanation:
(f-g)(x) = f(x)-g(x)
= (5x²-3) - (x²-4x-8)
=5x²-3 -x² +4x +8 ( - sign outside will multiply each sign inside)
=4x² +4x + 5
The 3 angles of a triangle will add up to 180 degrees.
5x + 2x + 3 + 3x - 3 = 180...combine like terms
10x = 180
x = 180/10
x = 18
one angle is : 5(x) = 5(18) = 90 degrees
the other angle is : 2x + 3 = 2(18) + 3 = 39 degrees
the last angle : 3x - 3 = 3(18) - 3 = 51 degrees
I’m sorry I needed the point but u got this
Solve these equations the same as solving multistep equations,
for example
#6.
Add six to both sides
now the inequality says
f < 5
now solve the second equation
F-4 Is equal to, or greater than 2
Add four to both sides
now the equation says:
F is equal to, or greater than 6
so your two answers are
f < 5 and F is equal to, or greater than 6
